and broadcasts its own routing information on those same networks. The SSR supports
the following Interior Gateway Protocols:
• Routing Information Protocol (RIP) Version 1, 2 (RFC 1058, 1723)
• Open Shortest Path First (OSPF) Version 2 (RFC 1583)
Exterior Gateway Protocols are used to transfer information between different
“autonomous systems”. The SSR supports the following Exterior Gateway Protocol:
• Border Gateway Protocol (BGP) Version 3, 4 (RFC 1267, 1771)
Multicast Routing Protocols
IP multicasting allows a host to send traffic to a subset of all hosts. These hosts
subscribe to group membership, thus notifying the SSR of participation in a multicast
transmission.
Multicast routing protocols are used to determine which routers have directly attached
hosts, as specified by IGMP, that have membership to a multicast session. Once host
memberships are determined, routers use multicast routing protocols, such as DVMRP,
to forward multicast traffic between routers.
The SSR supports the following multicast routing protocols:
• Distance Vector Multicast Routing Protocol (DVMRP) RFC 1075
• Internet Group Management Protocol (IGMP) as described in RFC 2236
The SSR also supports the latest DVMRP Version 3.0 draft specification, which
includes mtrace, Generation ID and Pruning/Grafting.
Configuring IP Interfaces and Parameters
This section provides an overview of configuring various IP parameters and setting up
IP interfaces.
Configure IP Addresses to Ports
You can configure one IP interface directly to physical ports. Each port can be assigned
multiple IP addresses representing multiple subnets connected to the physical port.
To configure an IP interface to a port, enter one of the following commands in
Configure mode.
Configure an IP interface to a physical
port.
interface create ip <InterfaceName>
address-mask <ipAddr-mask> port <port>
